Magnesium is extracted in one of three ways. The first is the electrolytic process, which uses magnesium chloride produced from magnesite or seawater. The second is the silicothermic process, which mixes calcined dolomite or magnesite with ferrosilicon alloy. The third involves dissolving magnesite in hydrochloric acid to make magnesium chloride.

How Is Magnesium Extracted?, Reference. Magnesium is extracted in one of three ways. The first is the electrolytic process, which uses magnesium chloride produced from magnesite or seawater. The second is the silicothermic process, which mixes calcined dolomite or magnesite with ferrosilicon alloy.
Magnesium: extraction; Brife introduction; Magnesium is found in solution in seawater (about kg m3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (). Both of the two types of resources can be used as raw materials to manufacture magnesium metal.
